What would you do if I told you your partner that day was me? Gen, a hairdresser, has long been in love with his older childhood friend, Koutarou, who likes his older brother, Kanade. One night, Gen spends the night at a hotel with a drunken Koutarou, bolstered by the thought that he might have a chance. However, Koutarou mistakenly thinks it was his older brother, Kanade, that he slept with. Gens used to being mistaken as Kanade, but they felt each others heat to think he was mistaken as him even at night. A devoted, younger, handsome hairdresser x a naturally airheaded, devilish, older, plain-faced boys one-sided, childhood love!
